Abstract

Programming application of master/slavery station of Modbus RTU protocol by S7-200 PLC is proposed originally from the engineering requirements.Due to its free and integrated Modbus RTU library,the S7-200 acts as a media device in the automation area including Modbus as a typical example.It shows that the method in this paper has a good practical value.
